assuming the septum is the really tough string like thing that runs right down the middle of your penis, then wouldnt bends/twists be doing the wrong thing? surely stretches straight out would work this most. im willing to bet that a rhytHydromaxical pulling SO action is the way to go on this one. rhytHydromaxical, simply because you WILL exert more pressure than if you just did one "100%" pull. so maybe DLDS pulse 110s? just a thought...
